Elucidate genetic regulation of GBM differentiation

胶质母细胞瘤（GBM）是原发性脑癌中最常见和最具侵袭性的形式， 预后迫切需要改善这种疾病治疗的新方法。积累 有证据表明，这种疾病缺乏有效的治疗是因为现有的治疗方案不能 有效消除胶质母细胞瘤干细胞（GSC），GBM发展的根源。一个有希望的方法是 是诱导GSC分化。不幸的是，分化疗法的发展 由于我们对GSC分化的生物学认识不足，在本申请中， 我们建议描述GSC分化的遗传调控，并验证可以靶向的基因， 用于有效的GBM分化治疗。作为初步工作，我们确定了一组基因， 通过RNAi筛选和单细胞筛选的组合调节GSC向特定谱系分化 RNA测序方法。在本申请中，我们将表征导致GSC分化调节 目的1中的候选基因，并确定所选基因对GSC分化的治疗潜力 治疗目标2。该项目的成功将导致鉴定新的GSC分化调节剂， 可以潜在地用于改善GBM的治疗。

Glioblastoma (GBM) is the most common and aggressive form of primary brain cancer with extremely poor prognosis. New approaches for improved treatment of this disease are desperately needed. Accumulating evidence suggests that the lack of effective treatment for this disease is because the existing regimens cannot effectively eliminate glioblastoma stem cells (GSCs), the root of GBM development. One promising approach to eliminating GSCs is to induce GSC differentiation. Unfortunately, the development of differentiation therapy for GBM has been limited by our poor understanding of the biology of GSC differentiation. In this application, we propose to characterize genetic regulation of GSC differentiation and validate genes that can be targeted for effective GBM differentiation therapy. As preliminary work, we identified a group of genes, which potentially regulate GSC differentiation toward specific lineages through a combination of RNAi screening and single-cell RNA sequencing approach. In this application, we will characterize lead GSC differentiation regulatory candidate genes in Aim 1, and to determine the therapeutic potential of selected genes for GSC differentiation therapy in Aim 2. Success of this project will lead to identification of novel GSC differentiation regulators that can be potentially targeted for improved treatment of GBM.
